What are the technical features of rice field eel cage culture?

Answer: In the cage culture model for rice field eels, the bottom of the cage is completely soil-free, and the rice field eels live entirely on the floating rafts of aquatic plants inside the cage. It has the characteristics of occupying less water surface, fewer diseases, a high survival rate, fast growth, easy management, and easy harvesting. The disadvantages are that it is difficult to clear residual matter, and the eels are prone to freezing damage during overwintering. In the northern regions of China, using existing intensive culture ponds or reservoirs to develop deep-water soil-free cage culture of rice field eels is very feasible and highly promising.
